Industrial RES150 Fuse

The RES-150 Super-Lag Renewable Fuse from Bussmann (now Eaton Bussmann) is a rugged 150-amp, 600-volt time-delay fuse designed for industrial and renewable-energy installations where short-circuit currents are relatively modest and reliability under frequent inrush conditions is essential. As a non-current-limiting Class H fuse, it leverages a long time-delay (Super-Lag) profile to tolerate startup surges and intermittent faults without nuisance blowing, while still delivering robust protection against sustained faults that could damage conductors and equipment. With an interrupting rating of up to 10 kA at 600 VAC, this fuse is typically paired with RES-150 Class H/K5 fuse blocks or compatible fuse links—such as the 9.63-inch LKS-150 fuse links—that form the complete protection assembly used in industrial feeders and renewable-energy distribution. Operating in typical industrial environments, it is designed for inline or holder-based configurations within Bussmann's renewable fuse ecosystem and the RES-150 family of protection devices.
